As the great Rage Against the Machine lyric goes, "We don't need the key, we’ll break in." Alas, I don't think Zack de la Rocha had Arc Raiders in mind when penning 'Know Your Enemy,' but the reference stands at the moment thanks to a glitch letting players avoid locked doors for loot.
Maps in Arc Raiders have keycards for corresponding rooms full of treasure. It gives you a reason to explore, for both the keys and their doors. But, an exploit is letting players phase through the fortified entryway and open it from the inside.
